The spandrel portion 70 includes, for example, a glass curtain wall constituting the outer surface side of a building having a glass panel 72, a mullion 74, and a transom light 73, and a spandrel composed of a wooden wall material 1 joined to a steel pillar 3. , An upper support member 75 that connects the upper end side of the spandrel and the upper transom light 73 facing the upper end side of the spandrel to support the upper transom 73 on the spandrel, and the lower end side of the spandrel and the lower end of the spandrel. It is configured to include a lower support member 76 that connects a lower transom 73 facing the side and supports the lower transom 73 on a spandrel.
The mullion 74 is fixed to the span drain or the floor 62 by, for example, a fixing means (not shown).
Further, both ends of the transom light 73 in the horizontal direction are fixed to the mullion 74 via a connecting means (not shown).
Further, in the upper support member 75 and the lower support member 76, the outer surface side of the building is connected to the transom light 73, the indoor side is provided with a rail 77, and the indoor side is supported by the spandrel via the rail 77. ..

A 60-minute semi-fireproof structure can be realized by using, for example, a wooden board having a thickness of 60 mm or more as the wooden wall material 1 constituting the spandrel. That is, a semi-fireproof structure can be secured by the thickness of the burning allowance of wood.
Further, the upper support member 75 and the lower support member 76 are made to have a fireproof structure by subjecting the upper support member 75 and the lower support member 76 to fireproof treatment such as spraying rock wool.
That is, the spandrel portion 70 having a semi-fireproof structure can be constructed by using a wooden plate material corresponding to the semi-fireproof structure as the wooden wall material 1 constituting the spandrel and subjecting the upper support member 75 and the lower support member 76 to fireproof treatment. ..

According to the building provided with the spandrel portion 70, when the building is viewed from the outside of the building, the wooden wall material 1 constituting the spandrel can be visually observed through the glass panel 72 of the glass curtain wall of the spandrel portion 70, and the building. It is possible to make a building with an excellent exterior design in which the wood texture of the wooden wall material 1 can be visually observed from the outside of the building.
Further, when the spandrel portion 70 is viewed from the indoor side, the wood texture of the wooden wall material 1 constituting the spandrel can be visually observed, and the building can be made into a building having an excellent indoor design that can improve the working environment.

Further, conventionally, a calcium silicate board (fireproof board) is often used as the spandrel (see, for example, Japanese Patent Application Laid-Open No. 2011-190614). However, it is known that dew condensation occurs on the glass panel surface due to the moisture absorption and desorption action of the calcium silicate plate (for example, "Condensation simulation program for designing glass curtain wall spandrel part and its accuracy verification", Takashi Gondo. , Kuniaki Mihara, Masahiko Oyama, Shuichi Kumai, Environmental Papers of the Japan Society for Architecture, Vol. 81, No. 726, 687-696, August 2016).
On the other hand, according to the building provided with the spandrel portion 70 described above, since the spandrel is made of the wooden wall material 1, dew condensation is less likely to occur on the glass panel surface as compared with the case where the spandrel is made of a calcium silicate plate. You can also get the effect of becoming.
